Definition

This syndrome has characteristics of mild intellectual deficit, failure to thrive, short stature and osteopoikilosis. It has been described in four unrelated patients. The syndrome appears to be caused by a heterozygous deletion at chromosome region 12q14, which was detected in three of the four patients. The deleted region contains the LEMD3 gene: mutations in this gene have already been implicated in osteopoikilosis. [from SNOMEDCT_US]
